Sony has advised consumers to stop using some of its VAIO laptop computers and unplug them, saying that it’s possible that its non-removable battery pack could overheat, the Associated Press has reported. The packs included in some of Sony’s Vaio Fit 11A models, which were released in February, were provided by a third-party supplier, said Sony. If the packs overheat, it could cause burns to the laptop’s housing, it said. The recall affects computers with the product name “SVF11N1XXXX.” The company said it’s in the process of creating a programme to repair or replace the computers, or will refund their purchase price.
